The translation would be something like "It doesn't matter if he's the dragon god, he can't bring [someone] back to life."

Here's the breakdown:
いくら - how much
神龍 - Dragon god (are you sure this isn't 龍神? normally, the 神 kanji comes last in animal God names)
といえど - if you say
こ…これでは - th...this (situation)
もう復活はさせられまい!! -- to not be able to do have something done to you.

The last one is kind of difficult, but it's the core verb to be reborn 復活 with the negative まい of a causitive passive させられる. The は in there stresses the 復活.

It is 神龍. The furigana say it is pronounced "shen ron", which according to a source, is "Shen Long" which is Chinese. The sentence is from a Dragon Ball manga. I'm a little confused--your first translation is much different from the breakdown. What is the いくら all about. And what about the といえど. Also I don't understand the まい as a negative.
Is the "mai" a slang thing, because I've never seen that.
